Theodore, I'm not familiar with D2W so my understanding of the rules is very basic.
Yes, the idea is to use sortedBooks as a list of possible book for a person. I would not compute it in awakeFromFetch though because it will be computed every time the EO is fetched even just to display it's name on a list. I would create a sortedBooks() method instead.
